Taking the Quality Assurance engineer career path can be challenging as a learning experience, but the switch prepares you for where software development is headed while future-proofing your job.
This article explores how to move from manual testing to automation testing, to expand your skillset and career opportunities.
Difference Between Manual and Automated Testing
Let’s examine the difference between manual and automated testing to discover what you need to become proficient at to become an effective automated tester.
Manual testing refers to the traditional way of testing software by manually running tests without scripts or automated tools. Manual testers get under the hood to find defects in a manner that automated tests may miss.
Automated testing will continue to improve, but manual testing is usually needed when evaluating things like the user experience or user interface. The transition to automation attempts to speed up the process and reduce human mistakes and the challenge of scaling up complex projects.
Automation testing, on the other hand, sees testers use automation tools and frameworks to carry out comprehensive tests. These tools can improve the tests' speed, efficiency, coverage, and accuracy. That is especially true for complex scenarios, regression testing, repetitive tasks, etc.
